Video signal format for post-production

1. A method of generating a gateway video signal, comprising the steps of: inputting film frames recorded at a real-time rate representing a motion picture when reproduced at a real-time rate to a telecine converter that normally converts film frames recorded at a frame/second rate which is substantially higher than said real-time rate into a video signal having a field/second rate thereby speeding up the input of said frames at a higher rate of 1.2 to 1.25 times said real-time rate; converting the sped up frames input to said telecine converter to said gateway video signal at said field/second rate without adding video fields, thereby generating said gateway video signal at 1.2 to 1.25 times said real-time rate; and recording said gateway video signal on a recording medium at said higher rate, such that when the gateway video signal is reproduced from said recording medium at said higher rate, reproduced video appears at 1.2 to 1.25 times the real-time rate.

2. The method of claim 1, wherein the step of speeding up the input of said frames speeds up the input to 1.25 times said real-time rate.

3. The method of claim 1, further comprising the steps of: reproducing said gateway video signal at said higher rate; applying the reproduced gateway video signal to an electron beam recorder that normally records on film at said higher rate, said electron beam recorder then recording images represented by said gateway video signal on film at said higher rate, whereby when said film is reproduced at said real-time rate, reproduced video appears at the real time rate.

4. The method of claim 1, further comprising the steps of: reproducing said recorded gateway video signal at said higher rate; performing post-production processing on said reproduced gateway video signal; and recording the post-production processed gateway video signal.

5. The method of claim 4 wherein said post-production processing is performed at said higher rate.

6. The method of claim 4 wherein said recording of said post-production processed gateway video signal is performed at said higher rate.
